a) HNO3 + H2O → H3O+ + NO3 − HNO3 is the Lewis base


b) HCN + CO3 2− ↔ CN − + HCO3 − HCN is the Lewis acid


c) SO2 + 2H2O ↔ H3O + + HSO3 − Water is both a Lewis acid and a Lewis base


d) H2CO3 + H2O ↔ HCO3 − + H3O + water is the Lewis acid


e) HSO4 − + H2O ↔ H3O + + SO4 2− Water is the Lewis base

My hip has been hurting a lot ever since i took a foul in a basketball game. My cluster is going on a field trip to some amusement park. I will not be with a teacher all the time. I will be with my friends. I'm afraid my hip might give out. If this happens what do i do? Go to the first aid station? Have the first aid guy come to me? If I go to the first aid station will the guy talk me through it? How do i ask him for help without being embarrassed?

I know it's long but thank god for people who actually read the question!
